Starting Operation
To switch on the power tool, press the lock-off button (5) next to the symbol 
first, thereby deactivating it. Then press the on/off switch (6) and keep it pressed.
The worklight lights up when the on/off switch (6) is lightly or fully pressed allowing the work area to be illuminated in poor lighting conditions.
- Do not look directly into the worklight; it can blind you.
To switch off the power tool, release the on/off switch (6). Activate the lock-off button (5) by pressing the lock-off button next to the symbol 
.
You can variably adjust the stroke rate of the power tool when it is on by pressing in the on/off switch (6) to varying extents.
Applying light pressure to the on/off switch (6) results in a low stroke rate. Applying increasing pressure to the switch increases the stroke rate.
You can preselect the stroke rate and change it during operation using the stroke rate preselection thumbwheel (7).
The required stroke rate is dependent on the material and the work conditions and can be determined using practical tests.
It is recommended that you reduce the stroke rate when placing the saw blade on the workpiece and when sawing plastic and aluminium.
During prolonged periods of use at a low stroke rate, the power tool may heat up significantly. Remove the saw blade and let the power tool run at the maximum stroke rate for around three minutes to cool down.

In normal conditions of use, the power tool cannot be overloaded. If the power tool is overloaded or not kept within the permitted battery temperature range, the speed is reduced or the power tool switches off. At reduced speed, the power tool will run again at full speed once the permitted battery temperature is reached or the load is reduced. If it automatically shuts down, switch the power tool off, allow the battery to cool down, then switch the power tool back on.
